Vbox6.18 doesn't allow VM config change

[Fujitsu_user]

After I moved a set of VMs from the old laptop to a new AMD 5800x based dekstop, VMs couldn't start because of a hardware support issue, but the issue with "System Acceleration page:" is the key problem: we can't get this one off no matter what I set on the "System/Acceleration" page, the error flag just won't turn off, and it in turn caused save of the config change not possible.

Thanks, your solution works, after I enabled SVM in the bios, even the bridged network issue is gone and everything looks ok now.
Thanks a lot.
